Are Sri Lankan rubies valuable?

Yes, Sri Lankan rubies are quite valuable, though they are usually a bit lighter in tone than the well-known deep-red Burmese rubies. You often see bright purplish-red or pinkish-red, and with high clarity, untreated Sri Lankan rubies can fetch very strong prices in the gem market.

Sri Lanka is much more famous for sapphires; still, it also produces extraordinary rubies. The borderline between a dark pink sapphire and a lighter ruby from Sri Lanka is frequently a topic of debate among gemmologists. But if a Sri Lankan corundum reaches the chromium saturation level that allows it to be certified as a true ruby, then its great crystal transparency, strong brilliance, and absence of thermal enhancement make it a premium investment stone.
